However, in Japan, OTC drug overdose has become a prominent social problem in recent years due to stricter regulations for other drugs, especially among young people, and APAP is an increasing cause of acute liver injury due to overdose. This report describes three consecutive cases of acute liver failure in young women (22, 22 and 19 years old) due to APAP overdose in December 2023. Despite severe liver injury, indicated by high ALT levels and coagulopathy, these cases recovered without requiring liver transplantation. This report discusses three cases of acute liver failure in young Japanese women following APAP overdose, reflecting a national increase in such cases due to increased misuse of OTC drugs and societal factors. Key findings include the need for early treatment with N-acetylcysteine (NAC) and the importance of mental health assessment in the management of overdose patients. The cases underscore the need for prompt team-based care to prevent serious outcomes and highlight the complexity of liver transplantation decisions in Japan, highlighting the need for comprehensive strategies to address the escalating problem of APAP overdose.</p>","PeriodicalId":10364,"journal":{"name":"Clinical Journal of Gastroenterology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141765688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We experienced a case of an early-stage type 3 gastric NET associated with lymphovascular and submucosal invasion. In a 54 year-old woman, esophagogastroduodenoscopy performed during a health screening identified an elevated lesion of the upper body of the stomach. The results of immunohistochemical analyses of endoscopic biopsy specimens obtained from the lesion were positive for chromogranin A and synaptophysin, indicating an NET. Because the patient's serum gastrin level was normal and she had no predisposing conditions for NET development, the tumor was diagnosed as a type 3 gastric NET. The patient underwent local resection of the tumor and regional lymph node dissection.
